Description

Technical Field

[0001] The utility model relates to the technical field of worm gear power storage, in particular to a worm gear power storage device provided with a self-lubricating mechanism. Background Art

[0002] A worm gear is a special gear that is usually used in conjunction with a worm to form a worm gear mechanism. It is used to transmit motion and power between two intersecting shafts. The worm gear is driven to rotate, thereby realizing the mutual conversion between mechanical energy and electrical energy. During the process of electrical energy conversion, the generated electrical energy can be stored through an electrical storage device.

[0003] During use, as the worm wheel and the worm rotate in meshing engagement, wear easily occurs at the meshing position, resulting in a problem of shortened service life of the worm wheel and the worm.

[0004] In order to overcome the above-mentioned defects, the prior art (publication number CN117189861A, Chinese patent application date 2023-12-08) is an electric drive generator device based on worm gear transmission. The front end of the housing is rotatably connected to a first rotating shaft, the rear end of the first rotating shaft is fixedly connected to a worm wheel, the top of the worm wheel is meshedly connected to a worm, and a mounting groove is provided at the top of the housing and above the worm. An oil tank is plugged into the interior of the mounting groove, and the bottom end of the oil tank is fixedly connected to an oil outlet pipe. A threaded hole is provided at the top of the oil tank, and a tank cap is fixedly installed on the top of the oil tank. By providing an oil tank that is easy to install and disassemble, the disassembled oil tank is easy to clean. The staff can add lubricating oil to the worm gear inside the device at any time to maintain the equipment.

[0005] The above mechanism adds an oil tank so that the staff can add lubricating oil to the worm gear through the oil tank, thereby reducing the wear of the meshing position. However, in actual use, only adding the oil tank requires the staff to manually add lubricating oil, resulting in low work efficiency and frequent lubricating oil addition. Utility Model Content

[0008] A connecting rod is provided on the left side of the top of the protection box, and an automatic lubrication mechanism for spraying lubricating oil on the worm and the worm wheel body is provided on the left side of the top of the protection box, the automatic lubrication mechanism includes a cam, and the cam is fixedly connected to the outer side of the connecting rod, the top of the protection box is provided with two extrusion plates, and an elastic air bag is provided on one side between the two extrusion plates, an oil storage box is installed on the top of the interior of the protection box, and the rear end of the elastic air bag is connected to the oil storage box through a hose, the interior of the oil storage box is slidably connected to a piston plate, and the bottom end of the oil storage box is provided with a nozzle;

[0010] Furthermore, the extrusion plates are slidably connected to the protective box, a connecting spring is provided between the two extrusion plates, and an elastic structure is formed between the two extrusion plates through the connecting spring.

[0011] Furthermore, the connecting springs are arranged at the front and rear ends of the elastic airbag, and the connecting springs are symmetrical about the vertical center axis of the elastic airbag.

[0012] Furthermore, heat dissipation grooves are provided at both the front and rear ends of the protection box, and the front end of the worm gear body extends to the outside of the protection box and is installed with a fan, which is arranged at the front end of the heat dissipation grooves.

[0015] Furthermore, the fan blades are connected to the screw rod via a belt transmission mechanism, and the fan blades are arranged above the screw rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The belt transmission mechanism drives the connecting rod and cam to rotate. When the cam rotates, it pushes the extrusion plate, which squeezes the elastic airbag. The gas inside the elastic airbag is transported to the inside of the oil storage box through the hose. The piston plate inside the oil storage box is squeezed and pushed by the increase of gas, and the lubricating oil stored below the oil storage box is squeezed and evenly sprayed onto the surface of the worm through the nozzle, thereby achieving automatic lubrication between the worm and the worm wheel body.

In addition, the continuous rotation of the fan can assist in blowing air and dissipating heat inside the protective box, reducing heat accumulation.

[0020] 2. The motor can drive the fan blades to rotate, and when the fan blades rotate, the belt transmission mechanism can drive the screw to rotate, so that the movable block drives the scraper to slide on the surface of the filter plate. The filter plate can filter the dripping lubricating oil to prevent the lubricating oil and impurities from accumulating in one place, affecting the secondary use of the lubricating oil;

[0021] Furthermore, the fan blades can guide the lubricating oil so that the lubricating oil is dispersed on the surface of the fan blades, thereby allowing the temperature of the lubricating oil to drop before filtering, thereby avoiding the situation where the hot lubricating oil is always stored inside the protective box, causing the temperature inside the protective box to rise and affect heat dissipation.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1-4 and Figure 6The technical solution shown is to solve the problem that when the worm wheel body and the worm are engaged and rotating, the meshing position is easily worn, resulting in a shortened service life of the worm wheel body and the worm: the worm wheel power storage device with a self-lubricating mechanism discloses an automatic lubrication mechanism, including a protective box 1, a worm 3 is rotatably connected between the left and right sides of the interior of the protective box 1, and a worm wheel body 4 is meshed below the worm 3, the left side of the worm 3 extends to the outside of the protective box 1 and is installed with an output rod 2, the worm wheel body 4 is rotatably connected between the front and rear ends of the interior of the protective box 1, a generator 7 is installed on the outside of the protective box 1 at the rear end of the worm wheel body 4, a connecting rod 8 is provided on the left side of the top of the protective box 1, and an automatic lubrication mechanism for spraying lubricating oil on the worm 3 and the worm wheel body 4 is provided on the left side of the top of the protective box 1. The automatic lubrication mechanism includes a cam 9, and the cam 9 is fixedly connected to the outside of the connecting rod 8. Two extrusion plates 10 are provided at the top of the protective box 1, and an elastic air bag 11 is provided on one side between the two extrusion plates 10. An oil storage box 13 is installed at the top of the inside of the protective box 1, and the rear end of the elastic air bag 11 is connected to the oil storage box 13 through a hose. The inside of the oil storage box 13 is slidingly connected with a piston plate 15, and the bottom end of the oil storage box 13 is provided with a nozzle 14. The extrusion plate 10 and the protective box 1 are slidably connected. A connecting spring 12 is provided between the two extrusion plates 10, and an elastic structure is formed between the two extrusion plates 10 through the connecting spring 12. The connecting spring 12 is provided at the front and rear ends of the elastic air bag 11, and the connecting spring 12 is symmetrical about the vertical center axis of the elastic air bag 11.

[0033] The worm 3 rotates and meshes with the worm wheel body 4, causing the worm wheel body 4 to rotate, thereby causing the worm wheel body 4 to drive the output end of the generator 7 to rotate, and then the battery is used to collect and store the converted electrical energy, and then the belt transmission mechanism can drive the connecting rod 8 and the cam 9 to rotate. When the cam 9 rotates, it pushes the extrusion plate 10, so that the extrusion plate 10 can squeeze the elastic airbag 11, so that the gas inside the elastic airbag 11 is transported to the inside of the oil storage box 13 through the hose, and the piston plate 15 inside the oil storage box 13 is pushed downward due to the increase of gas, so that the lubricating oil stored below the inside of the oil storage box 13 is squeezed and evenly sprayed on the surface of the worm 3 through the nozzle 14. Through the meshing between the worm 3 and the worm wheel body 4, the lubricating oil can be applied to the outside of the worm wheel body 4 through the meshing relationship, thereby realizing automatic lubrication and avoiding manual addition of lubricating oil by the staff.

[0034] Example 2:

[0035] like Figure 1-Figure 3 and Figure 5The technical solution shown is to solve the problem of high heat generation between the worm 3 and the worm wheel body 4 during meshing: the worm wheel power storage device provided with a self-lubricating mechanism discloses a heat dissipation mechanism, and heat dissipation grooves 6 are provided at the front and rear ends of the protective box 1, and the front end of the worm wheel body 4 extends to the outside of the protective box 1 and is installed with a fan 5, which is arranged at the front end of the heat dissipation groove 6.

[0036] In this example, the heat dissipation groove 6 can assist in achieving ventilation and heat dissipation inside the protective box 1, avoiding the problem of temperature rise caused by friction between the worm 3 and the worm wheel body 4 after multiple engagements, thereby extending the service life of the worm 3 and the worm wheel body 4 when in use, and the continuous rotation of the fan 5 can assist in blowing air to dissipate heat inside the protective box 1, reducing heat accumulation.

[0037] Example 3:

[0038] like Figure 1-Figure 3 and Figure 5-Figure 7 The technical solution shown is to solve the problem that after the worm 3 and the worm wheel body 4 are lubricated by the automatic lubrication mechanism, some excess lubricant will drip into the interior of the protective box 1, causing the interior of the protective box 1 to be dirty: the worm wheel power storage device with a self-lubricating mechanism discloses a collection mechanism, a collection box 16 is installed at the bottom end of the interior of the protective box 1, and a collection mechanism for collecting and filtering excess lubricating oil is provided inside the collection box 16, and the collection mechanism includes a filter plate 21, and the filter plate 21 is provided on the collection box 1 6, a fan blade 17 is rotatably connected between the front and rear ends of the collection box 16, and a screw rod 18 is rotatably connected between the front and rear ends of the collection box 16. The outer side of the screw rod 18 is threadedly connected to a movable block 19, and a scraper 20 is installed at the bottom end of the movable block 19. The bottom end of the scraper 20 is in contact with the surface of the filter plate 21, and the width of the scraper 20 is equal to the width of the filter plate 21. The fan blade 17 and the screw rod 18 are connected by a belt transmission mechanism, and the fan blade 17 is arranged above the screw rod 18.

[0039] In this example, after the lubricating oil is sprayed, some of the lubricating oil may drip due to excessive spraying. Excessive lubricating oil dripping into the interior of the protective box 1 will cause dirt. In order to ensure the cleanliness of the interior of the protective box 1 during use, the motor can drive the fan blade 17 to rotate. When the fan blade 17 rotates, it can drive the screw 18 to rotate through the belt transmission mechanism. The screw 18 is threadedly connected to the outer movable block 19, and the movable block 19 drives the scraper 20 to slide on the surface of the filter plate 21. The filter plate 21 can filter the dripping lubricating oil to prevent the lubricating oil and impurities from accumulating in one place, which affects the secondary use of the lubricating oil.

[0040] The fan blades 17 can guide the lubricating oil so that the lubricating oil is dispersed on the surface of the fan blades 17, so that the temperature of the lubricating oil can be reduced before filtering, thereby avoiding the hot lubricating oil being always stored inside the protective box 1, causing the temperature inside the protective box 1 to rise and affect heat dissipation.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
